Description

[Technical field]

[0001] The present invention relates to a small anchor-integrated liner that is attached around anchor bolts for mounting equipment and / or a rack (on both sides of the anchor bolts for mounting equipment and / or a rack) that protrude from a concrete slab surface, a wall surface, or the top surface of reinforced concrete for a machine foundation, to adjust the installation height of the equipment. [Background technology]

[0002] Fig. 9 is an explanatory diagram of a conventional equipment installation centering method using a flat liner, a gradient liner, and a conventional anchor-integrated liner. When installing equipment (also called a machine tool) 1 on the upper surface of a machine foundation reinforced concrete 2 (hereinafter sometimes simply called concrete), fine adjustment in the height direction is performed using a combination of a flat liner 3 and a gradient liner 4 on the upper surface of the concrete 2 (see the left side of the figure), or using the applicant's conventional anchor-integrated liner 5 shown in Patent Documents 1 and 2 (see the right side of the figure). In the conventional equipment installation method, a flat liner 3 is placed on top of the concrete by piling up an appropriate amount of cement, which is then pressed evenly with the flat liner 3 and firmly fixed in place while ensuring horizontality with a spirit level, and the height is then adjusted with a gradient liner 4. However, for small pumps, lightweight equipment, mounting bases, etc. other than those requiring high installation precision such as large pumps, it is often the case that a flat liner is placed directly on top of the concrete and liners are stacked on top of each other.

[0003] Specifically, the installation and centering of such simple equipment / racks are performed as follows (1) to (4). (1) Attach the anchor bolts 7 for mounting the equipment and rack to the reinforced concrete machine foundation 2. (2) Attach the back nut 6 to the anchor bolt 7 for mounting the equipment / rack to determine the height of the equipment base. (3) Stack several flat liners 3. Fine-tune with gradient liners 4. Gradient liners may not be used. (4) Since it is prohibited for the back nut 6 to bear a load, loosen the back nut 6 to prevent the load from the base from acting on the back nut 6.

[0004] The problem at this time is that there is no adhesive strength between the back surface of the flat liner and the top surface of the concrete, so the contact surface between the flat liner 3 and the concrete moves during liner adjustment, making adjustment difficult (issue 1). The conventional anchor-integrated liner 5 was designed to prevent the position of the liner from moving, but when driving the anchor, if the equipment is temporarily placed, the anchor cannot be driven, so the conventional anchor-integrated liner 5 cannot be applied (issue 2). The flat liner 3 and the gradient liner 4 require more time for vertical adjustment than the liner part of the conventional anchor-integrated liner 5 (issue 3). It is difficult to maintain horizontality with the flat liner 3 as is (issue 4)

[0005] Furthermore, the gap between the top surface of the concrete on which the flat liner 3 and gradient liner 4 are installed and the underside of the machine base appears uniform but has significant irregularities (issue 5). For example, it is common that a gap of 30 mm is expected for one machine, but when construction is carried out it is 30 mm in some places and 40 mm in others. To deal with this, six to seven layers of flat liners 3 and gradient liners 4 are stacked. Generally speaking, it is common practice to stack three layers of flat liners 3 and gradient liners 4. There is a demand for liners that can accommodate such changes in height. In the conventional anchor-integrated liner 5 disclosed in Patent Documents 1 and 2, the anchor is driven into concrete, so that after the equipment 1 is installed in the concrete, it is not possible to insert the liner on the left and right sides of the anchor bolt 7 for mounting the equipment / rack through the gap on the side (issue 6).

[0006] [Patent Document 1] Patent No. 3775717 [Patent Document 2] Patent No. 4065957 Summary of the Invention [Problem to be solved by the invention]

[0007] In view of the problems 1 to 6 of the prior art, the problem that the present invention aims to solve is to provide a small anchor-integrated liner that facilitates centering of equipment after pouring reinforced concrete for a machine foundation. [Means for solving the problem]

[0008] As a first means for solving the above problems, the present invention provides a flat liner part having screw holes in three or more places on the main surface and anchor bolts that screw into the screw holes and have bolt tips protruding from one main surface, and a male thread portion protruding from the other main surface of the flat liner portion; a liner portion having a female thread and a liner surface on which an equipment base is placed and which is screwed into the male thread portion; The object of the present invention is to provide a small anchor-integrated liner, which is characterized in that the horizontal level of the flat liner can be adjusted with the anchor bolt and the installation height of the equipment base can be adjusted with the liner portion. According to the first means, the heights of the anchor bolts at three or more points on the main surface can be adjusted, so that the flat liner can be installed horizontally even if the concrete surface is uneven. The anchor bolts also function as stoppers, preventing the flat liner from sliding sideways when adjusting the position of the equipment or plate using the liner. Also, simply fitting the anchor bolts into the anchor holes makes it easy to align the marked position. In this case, when marking out the positions of the anchor bolts for mounting the equipment / frame on the top surface of the reinforced concrete of the machine foundation, mark out the opposing anchor holes in three or more places (for example, the four corners) on the main surface of the anchor-integrated liner and drill them into the top surface of the concrete. By injecting adhesive into the drilled holes and grounding the small anchor-integrated liner, it can be attached to both horizontal and vertical concrete surfaces. Effect of the Invention

[0009] According to the present invention, if the length of three or more anchor bolts is shorter than the small gap on the side, the liner can be attached by inserting it through the small gap on the side after the equipment is installed on the top surface of the reinforced concrete machine foundation, thereby shortening the adjustment work time for equipment installation and reducing construction costs.

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a small anchor integrated liner of the present invention will be described in detail below with reference to the drawings.

[0012] [Small anchor integrated liner 10] Fig. 1 is a perspective view of a small anchor-integrated liner of the present invention, and Fig. 2 is an explanatory view of how to install the small anchor-integrated liner of the present invention. The small anchor-integrated liner 10 of the present invention is equipped with a flat liner portion 20 having threaded holes in three or more places on its main surface and an anchor bolt 50 which screws into the threaded holes and has its bolt tip protruding from one of its main surfaces, a male threaded portion 30 which protrudes from the other main surface of the flat liner portion 20, and a liner portion 40 having a female thread which screws into the male threaded portion 30 and has a liner surface on whose upper surface an equipment base can be placed. The flat liner portion 20 is a metal flat plate having a polygonal shape (FIG. 1 shows a square shape), a circle, an ellipse, etc. in a plan view. The flat liner portion has a male thread portion 30 provided at the center of the surface. The male thread portion 30 is a screw member with a diameter of 12 mm to 80 mm and a threaded outer periphery. The male thread portion 30 is welded to the center of one of the main surfaces of the flat liner portion 20, or is threaded through a center hole, or is welded through a center hole. When threaded, the diameters of the threads are not necessarily the same.

[0013] The flat liner portion 20 is provided with an anchor bolt 50. The anchor bolt 50 is set shorter than the gap between the machine foundation reinforced concrete 2 and the equipment or plate, in other words, the foundation grout, and is set within several tens of mm as an example. Four anchor bolts 50 are formed at the four corners of the flat liner portion 20 as shown in FIG. 1, but it is not limited to this and it is preferable to provide at least three or more on the main surface. An anchor hole 52 into which the anchor bolt 50 fits is drilled on the upper surface of the machine foundation reinforced concrete. The anchor bolt 50 is a bolt consisting of a head and a threaded shaft. The flat liner portion 20 is provided with a screw-in hole into which the anchor bolt 50 is screwed. The head side is disposed on the surface of the flat liner portion 20, and the tip of the shaft protrudes from the back surface of the flat liner portion 20. The anchor bolt 50 is screwed into the flat liner portion 20, but the unevenness is adjusted by the protrusion of the anchor bolt 50, so the thread length of the anchor bolt 50 and the positional relationship of the flat liner may vary.

[0014] The liner part 40 screws into the male thread part 30 to form a mounting surface for equipment or a plate on its upper surface. The mounting surface of the liner part 40 may have any shape as long as it can withstand the load of the equipment, for example, a circular or polygonal shape is adopted. The liner part 40 also has a blind hole formed inside and has a threaded inner surface. The liner part 40 can be screwed into the male thread part 30 and moved up and down to adjust the installation height of the equipment or plate. The liner part 40 is also positioned so that its upper surface is at the same height as the back surface of the machine base. The circular liner part 40 has four rotation holes on its circumferential surface. Two opposing holes among the rotation holes 42 also serve as resin filling holes 44 and are inserted into the blind holes. The liner part 40 can be rotated by inserting a turning rod 43 into the rotation holes 42 or filling holes 44 to adjust the installation position of the device or plate.

[0015] [Variation 1] Hexagonal nut + screwed lid FIG. 3 is a side view of the small anchor-integrated liner of the first modified example. The small anchor integrated liner 10A of the first modified example has a liner portion 40A which is a hexagonal nut. The liner portion 40A is provided with a threaded lid 46 which covers the top surface of the nut. The other configurations are the same as those shown in Fig. 1-2. The threaded lid 46 is provided with a screw member 46b which protrudes from one main surface of a plate 46a. The thickness of the plate 46a can be freely set according to the gap between the reinforced concrete of the machine foundation and the equipment. The screw member 46b is a screw which screws into the hexagonal nut. The small anchor integrated liner 10A of the first modified example having such a configuration can reduce material costs by applying a commercially available hexagonal nut to the liner part 40A. In addition, by using a screw cap 46 that corresponds to the gap between the concrete and the equipment, the flexibility of the range of application can be expanded.

[0016] [Variation 2] Hexagonal nut, long thread FIG. 4 is a side view of a small anchor-integrated liner according to the second modification. The small anchor integrated liner 10B of the modified example 2 has a liner portion 40A which is a hexagonal nut similar to that of the modified example 1. The length of the male thread portion 30A is longer than the male thread portion 30 shown in FIG. 1-2 and can be arbitrarily set according to the gap between the machine foundation reinforced concrete and the equipment. The compact anchor integrated liner 10B of the modified example 2 having such a configuration can reduce material costs by applying a commercially available hexagonal nut to the liner portion 40A. In addition, by using the male thread portion 30A according to the gap between the concrete and the equipment, the flexibility of the range of application can be expanded.

[0017] [How to install the equipment] Fig. 5 is an explanatory diagram 1 of the installation method of the device of the present invention. Fig. 6 is an explanatory diagram 2 of the installation method of the device of the present invention. Fig. 7 is an explanatory diagram 3 of the installation method of the device of the present invention. Fig. 8 is an explanatory diagram 4 of the installation method of the device of the present invention. The mounting position of the small anchor integrated liner 10 is marked out on the upper surface of the reinforced concrete machine foundation 2. The mounting position of the anchor hole 52 of the anchor bolt 50 is also marked out, and the anchor hole 52 is drilled. The equipment is placed on the top surface of the reinforced concrete machine foundation 2. At this time, back nuts 6 are installed on the anchor bolts 7 for equipment / installation installation installed on the top surface of the reinforced concrete machine foundation 2, and then the equipment is temporarily placed. The anchor bolts 7 for equipment / frame installation are either set together with the reinforced concrete machine foundation 2 in advance, or are set in place after concrete has been filled into the box-cut holes.

[0018] The small anchor integrated liner 10 is inserted into the gap between the equipment and the reinforced concrete of the machine foundation and aligned with the marked position. Mortar, non-shrink mortar, or adhesive is injected between the bottom surface of the flat liner portion 20 and the top surface of the reinforced concrete machine foundation 2 to fix the liner portion 20 in place. At this time, a level 60 is placed against the liner portion 40 and the anchor bolt 50 is rotated to adjust the level (see FIG. 8). With the flat liner portion 20 clamped and fixed with a fixed spanner 70, the turning rod 43 is inserted into the rotation hole 42 or the filling hole 44 of the liner portion 40 and rotated to raise the liner portion 40, and the back nut 6 is loosened before adjusting the installation position of the equipment and performing centering work (see Figure 7). After the centering of the device is completed, epoxy resin is injected into the filling hole 44 of the liner portion 40 and it is confirmed that the resin comes out of the opposing filling hole 44. The locking spanner 70 is removed and the job is completed. According to the compact anchor-integrated liner 10 of the present invention, when adjusting the position of the equipment or plate using the liner part 40, the anchor bolt 50 can function as a stopper without causing the flat liner part 20 to slip sideways. Also, simply by fitting the anchor bolt 50 into the anchor hole 52, the positioning of the marked out position can be easily performed.

[0019] The small anchor-integrated liners 10, 10A, and 10B of the present invention can be used as permanent liners to be attached around anchor bolts for mounting equipment and racks that protrude from the top surface of the reinforced concrete for the machine foundation, and can also be used as temporary liners when placing a plate on the top surface of the reinforced concrete for the machine foundation where a box-punch hole is provided.

[0020] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and various modifications can be made without departing from the spirit and scope of the present invention. Furthermore, the present invention is not limited to the combinations shown in the embodiments, but can be implemented in various combinations. [Explanation of symbols]
